On some hv_sock workloads which quickly open/close many connections occasionally, channel IDs would get re-used while still having work pending. This can cause a kernel crash on a NULL pointer exception. The three patches added to the 4.9.x and 4.10.x kernels fixes these bugs. The patches are being prepared to be upstreamed, but for now we cherry-picked them from the developers tree. Signed-off-by: Rolf Neugebauer <rolf.neugebauer@docker.com>

Subject: [PATCH 03/10] Drivers: hv: utils: Fix the mapping between host
|
|
version and protocol to use
|
|
|
|
We should intentionally declare the protocols to use for every known host
|
|
and default to using the latest protocol if the host is unknown or new.
